Frequently asked questions about denufosol tetrasodium

What is denufosol tetrasodium used for?

Denufosol tetrasodium is an investigational inhaled therapy that was studied for the treatment of cystic fibrosis lung disease. It was evaluated in patients with mild cystic fibrosis as well as in pediatric patients aged 2 years and older. It is not an approved treatment.

How does denufosol tetrasodium work?

Denufosol tetrasodium is a small molecule agonist of P2RY2, a purinergic receptor. By activating this receptor, the drug was designed to stimulate chloride and fluid secretion in the airways, which was intended to improve mucus clearance in patients with cystic fibrosis lung disease.

Who is developing denufosol tetrasodium?

Denufosol tetrasodium was developed by Merck & Company, Inc., which trades under the ticker MRK. The company sponsored the clinical development program for the drug in cystic fibrosis.

What phase is denufosol tetrasodium in?

Denufosol tetrasodium reached Phase 3 clinical development for cystic fibrosis. Seven clinical trials have been completed, including two Phase 3 studies, and no trials are currently active. The drug is investigational and has not been approved for any indication.

What clinical trials is denufosol tetrasodium in?

Denufosol tetrasodium has been studied in seven completed trials, including NCT00625612, a Phase 3 study in cystic fibrosis lung disease with 466 patients, and NCT00357279, a Phase 3 study in mild cystic fibrosis lung disease with 352 patients. Pediatric studies include NCT01181622 and NCT00130182.

Is denufosol tetrasodium the same as INS37217?

Yes. Denufosol tetrasodium is also known as INS37217. The names denufosol tetrasodium (INS37217), denufosol tetrasodium (INS37217) Inhalation Solution, denufosol tetrasodium Inhalation Solution, and Denufosol Tetrasodium (INS37217) Inhalation Solution all refer to the same investigational compound.
